How Do You Multiply Fractions by Multiplying the Numerators and Denominators?

When you're learning to multiply fractions, it's pretty simple. You just need to follow a few easy steps. Let’s break it down!

Step-by-Step Guide to Multiplying Fractions

  1. Find the Fractions: Let’s say we want to multiply two fractions, like 23\frac{2}{3} and 45\frac{4}{5}.

  2. Multiply the Top Numbers: Start by multiplying the top numbers (called numerators) together. For our example: 2×4=8.2 \times 4 = 8.

  3. Multiply the Bottom Numbers: Next, multiply the bottom numbers (called denominators) together: 3×5=15.3 \times 5 = 15.

  4. Make the New Fraction: Now, put the results together to create a new fraction: 815.\frac{8}{15}.

Another Example

Let’s try another example to make this clearer. This time, we have the fractions 14\frac{1}{4} and 37\frac{3}{7}.

  1. Multiply the Top Numbers: 1×3=3.1 \times 3 = 3.

  2. Multiply the Bottom Numbers: 4×7=28.4 \times 7 = 28.

  3. Put It Together: 328.\frac{3}{28}.

So, when you multiply 14\frac{1}{4} by 37\frac{3}{7}, the answer is 328\frac{3}{28}.

Tips for Simplifying

Sometimes, after multiplying, you can make the resulting fraction simpler. Here’s how:

  • Look for Common Factors: Before multiplying, check if you can simplify the fractions by getting rid of common factors. For example, let’s look at 24\frac{2}{4} and 38\frac{3}{8}.
  1. Simplify: 24=12\frac{2}{4} = \frac{1}{2} (Divide both the top and bottom by 2).

  2. Multiply: 12×38=316.\frac{1}{2} \times \frac{3}{8} = \frac{3}{16}.

Conclusion

Whenever you multiply fractions, just remember to multiply the top numbers together and the bottom numbers together. It’s like a fun little math adventure that gives you new fractions! Keep practicing with different examples, and soon you’ll be a champ at multiplying fractions!
